Decyltrichlorosilane

Description:

Decyltrichlorosilane is an organosilicon compound characterized by its long hydrophobic alkyl chain and three reactive chlorosilane groups. It typically appears as a colorless to pale yellow liquid and is known for its ability to form siloxane bonds upon hydrolysis, making it useful in surface modification and coating applications. The presence of the decyl group imparts hydrophobic properties, enhancing its utility in creating water-repellent surfaces. Decyltrichlorosilane is often employed in the synthesis of silane-based materials, as well as in the functionalization of various substrates, including glass, metals, and polymers. Due to its chlorosilane functionality, it reacts readily with moisture, releasing hydrochloric acid and forming silanol groups, which can further condense to form siloxane networks. Safety precautions are necessary when handling this compound, as it can be corrosive and harmful upon contact with skin or inhalation. Overall, Decyltrichlorosilane is a versatile chemical with significant applications in materials science and surface engineering.

Alkyl Silane - Conventional Surface Bonding
Aliphatic, fluorinated aliphatic or substituted aromatic hydrocarbon substituents are the hydrophobic entities which enable silanes to induce surface hydrophobicity. The organic substitution of the silane must be non-polar. The hydrophobic effect of the organic substitution can be related to the free energy of transfer of hydrocarbon molecules from an aqueous phase to a homogeneous hydrocarbon phase. A successful hydrophobic coating must eliminate or mitigate hydrogen bonding and shield polar surfaces from interaction with water by creating a non-polar interphase. Although silane and silicone derived coatings are in general the most hydrophobic, they maintain a high degree of permeability to water vapor. This allows coatings to breathe and reduce deterioration at the coating interface associated with entrapped water. Since ions are not transported through non-polar silane and silicone coatings, they offer protection to composite structures ranging from pigmented coatings to rebar reinforced concrete. A selection guide for hydrophobic silanes can be found on pages 22-31 of the Hydrophobicity, Hydrophilicity and Silane Surface Modification brochure.
